In 2020 we published 9 papers on habitat loss and fragmentation, sustainable farmlands, and road ecology.
On habitat loss and fragmentation, we updated the old “single small or several large” SLOSS debate (Fahrig 2020), showing that several small patches hold more species than few large ones. We found support for the Habitat Amount Hypothesis (Watling et al. 2020). And we showed that habitat loss and disturbance interact to affect forests (Lloren et al. 2020). We also put forward a landscape design with lots of small forest bits, for biodiversity conservation in populated regions (Arroyo-Rodriguez et al. 2020). And we critiqued recent sweeping changes that have weakened Ontario’s Endangered Species Act (Bergman et al. 2020).
For sustainable farmlands we showed large benefits of smaller fields for plant diversity (Alignier et al. 2020). We showed that farmland heterogeneity affects biodiversity as much as reducing intense practices like pesticides (Martin et al. 2020). We also showed that macro-invertebrates are not good indicators of agrichemicals (Collins & Fahrig 2020).
In road ecology we showed a huge bias in how authors infer the mechanisms causing road impacts on wildlife (Teixeira et al. 2020).
